The switch in Figure F7-43 has been open for a long time and is closed at \(t=0\). The circuit parameters are \(L=\) \(0.02 \mathrm{H}, C=0.1 \mu \mathrm{F}\), and \(V_{\mathrm{A}}=20 \mathrm{~V}\).
(a) Select values of \(R_{1}\) and \(R_{2}\) so that the circuit is critically damped.
(b) How would you change the resistors if you wanted the circuit to be underdamped? Repeat for overdamped.
(c) Run a Multisim simulation for the critically damped situation.
